MECHANICAL SHAKER FOR CERAMIC TILE.

Application filed April 4, 1925. Serial No. 20,823.

Our said invention relates to mechanical shakers for ceramic tiles and1t is an ob ect thereof to provide means for mounting a group of tilesin predetermined relation to each other, the retaining'means being hereshown as consisting of so-called mounting boards having spaces for thetiles with ridges between them.

A further object of the invention is to provide means for agitating theboards in different directions to settle the tiles in their respectivecells, with means for varying the amount of such agitating movement. 7

A further object of the invention is to provide a shaking table for themounting boards upon which the boards can be placed while the machine isin motion and from which they can also be removed without stopping themachine.

Referring to the accompanying drawings, which are made a part hereof andon which similar reference characters indicate similar parts,

Figure 1 is a transverse vertical section of the machine,

Figure l1,.a vertical section through the feeding hopper, a fragment ofwhich is shown in Fig. 2, and

Figure 12, a similar section'atright-angles to Fig. 11.

The framework of the machine, as shown,

is made up of a base plate 11 interconnected through cross-bars 12 withuprights l3, l3 and 14, 14, the two uprights 14, 14 are con nected by across-member 15 and the two uprights 13, 13 are connected by'across-mem' ber 16. Uprights 13 are connected to uprights 14 at theirupper ends by angle irons 17.

Upon angle irons 17 are mounted brackets 18 in which two separate anddistinct shafts 19, 19 are slidably and rotatably mounted, the twoshafts 19 being alined on one common axis. On each shaft 19 are mountedand fastened two brackets 20 which serve to support a shaker-board 21which is provided with cleats 22. Between the inner ends of shafts 19 isthe upper end of a rocker-arm 23 which rocks on a pin 24 mounted in abracket 25 which is carried on cross-member 15. The lower end of rockarm23 is provided with a slot 26 in which operates a block 27; block 27 isrotatably mounted on a bushing 28 which is clamped by means of a T-bolt29 to a slotted crankdisk 30 carried on a shaft 31. Bushing 28 may beclamped at different distances from the center line of shaft 31 therebyvarying its throw and thereby varying the amount of endwise movement ofshaker-board 21 as well as its speed of movement. Shaft 31 is carried inbearings 32 which are supported by a bar 33 on two of the cross-bars 12.Shaft 31 is driventhrough pulleys 34 and belt 35 from any'suitablevariable speed mechanism, as shown in the drawings.

A tilting or rocking oscillatory movement is imparted tothe'shaker-board 21 by the following mechanism: At one edge of the boardis fastened a helically grooved stub 36 over which is wound a flexiblemember, such as a spring 37, so that this flexible member will transmitto the shaker-board 21 the motion imparted to the flexible member by asliding rod 38 without interfering with the longitudinal reciprocatingor shaking movement of the board. The, sliding rod 38 is carried inbearing blocks 39 which are bolted to cross-member 16 and is grooved atits upper end in a similar manner to stub 36 and over it is wound thelower end of spring 37. The sliding rod 38 is connected through pin 38and connecting rod 40 to'a crank pin 41 which is clamped to a slottedcrank 42 in such a manner that the distance from the center of pin 41 tothe axis of the crank 42 may be adjusted to vary the degree and thespeed of oscillation of the shakerboard. Crank 42 is carried on shaft 43which is mounted in bearings 44 and is driven through pulley 45 and belt46 from any suitable variable speed mechanism, as shown on thevdrawings.

To protect the working mechanism of the machine it is provided with aboxing 47.

Referring toig. 5, the shaker-board 21 is provided at one edge with ametal strip 48, and at the other edge with a series of friction springs49, 50 and .51, which serve to retain mounting boards 52, 53 and 54,these three being part of a great number of mounting boards used inconnection with this machine. Ellhese boards are provided with cleats 55which straddle the shakerboard 2-1, as can ,be seen in Fig. 1. Furtherdetails of the mounting boards are hereinafter described.

.In theioperation of this machine accord ing to the embodiment ,of theinventionherein illustrated and described, tiles :are fed from a hopper56 onto a ,mounting board, e g-board 54L, which has been placed onshakenboard 21 bytbeingslid onto the end ofcthe same and is ,heldthereon by friction 'springel) bearing against one of the cleats 55.After being loaded, this board is moved farther along the =shaker-board21 in the direction of the arrow, so that its cleats straddlefrictionspring 50 and in its place is slipped another mounting board v53 whichuponbeing loaded is shoved over friction spring 50, the mounting board54; .being shovedehead of it and over friction spring mounting ,board(52 to be filled next is now placed under the hopper and at this timemounting board 54 is removed by ibeingslid olfthe other end ofshaker-board-2l, it havingqbeen on a suificient length of time to permitthe tile to .be distributed over it and to settle into the pattern whichmay ,be.outlined Ion the mounting board, thus completing onecycle ofoperation.

During the shaking operation someof the tiles fall (over the {edges ofthe boards and for the purpose of {reclaiming these thenachine'isprovided with a hopper construction fifi ,consistingof sides 57, ends 57and dividing ridges58 and 59 which vconduct the {tile .thus spilledthrough openings 60 under which may be placed suitable receptacles intowhich they may fall.

secured on the top face of the board 61, and the tiles are held in placeby these strips until the shaking operation has disposed of any surplustiles which have been dropped thereon from hopper 56, the borders 62permitting these to slide off.

The shaker-board is shown as being tapered at both ends for conveniencein putting on and taking off the mounting boards sides 67 and 69 nengerespectively tat two sides of theihopper ,into vertical depending mem70. a ,1 separat d by inclined floor p es 2 fe ic ryingofi dirta dfragment o b oken til s p sing threugh the screens 69.

The bottom of the hopper comprises a perforated section or screen 14pivoted at one side, as indicated at 75, that has secured thereto at itsopposite side ,a moyable chute Th h pp r comp ise At t ei w r ends t eincline 76 which coacts with a fixed chute '77 for not being operated,at whichtime tiles may,
